Group1
The device uses RF energy only for its internal function.
Therefore, its RF emissions are very low and are not likely to
cause any interference in nearby electronic equipment
RF emissions
CISPR 11
Class B
The device is suitable for use in all establishments, including
domestic establishments and those directly connected to the
public low-voltage power supply network

Warning:
1. The device should not be used adjacent to or stacked with other equipment. If adjacent or stacked use is
necessary, the device should be observed to verify normal operation in the configuration in which it will be used.
2.Use of accessories, transducers and cables other than those specified or provided by the
manufacturer of this equipment could result in increased electromagnetic emissions or decreased
electromagnetic immunity of this equipment and result in improper operation.
3. Portable RF communications equipment (including peripherals such as antenna cables and external
antennas) should be used no closer than 30 cm (12 inches) to any part of the CPAP, including cables
specified by the manufacturer. Otherwise, degradation of the performance of this equipment could
result.
